Smokeless TobaccoThursday, November 26, 2009
If youre considering making the switch from cigarettes to chewing tobacco because you think the smokeless version of tobacco wont hurt you, think again. Chewing tobacco also causes serious health problems. Dr. Edward Hill discusses a study that took a closer look at smokeless tobacco in todays 60 Second Housecall.
A single pinch of snuff may expose the user to the same amount of dangerous smoke-related chemicals found in the smoke of five cigarettes.
Researchers have identified new toxins and cancer-causing substances in smokeless tobacco and snuff, in addition to other known carcinogens, such as nitrosamines.
Sales of moist snuff have doubled over the past 25 years and many smokeless tobacco users mistakenly believe the products are less hazardous to their health because they do not expose the user to tobacco smoke.
The study showed that some of the most popular smokeless tobacco and snuff brands contain an additional 21 smoke-related polycyclic aromatic hydrocarbons, which are potent toxins and carcinogens.
According to the National Cancer Institute, smokeless tobacco contains 28 cancer-causing substances. Oral cancers are linked to use of smokeless tobacco. Per dose, more nicotine from smokeless tobacco is absorbed than from a cigarette. Use of smokeless tobacco can also lead to nicotine addiction.
